Abstract Klotho, initially introduced as an anti-aging protein, is expressed in the brain, pancreas, and most prominently kidney. The two forms of Klotho (membrane-bound soluble form) have diverse pharmacological functions such anti-inflammatory, anti-oxidative, anti-fibrotic, tumour-suppressive etc. membrane-bound form plays a pivotal role maintaining kidney homeostasis by regulating fibroblast growth factor 23 (FGF 23) signalling, vitamin D metabolism phosphate balance. deficiency has been linked with significantly reduced protection against various pathological phenotypes, including diabetic disease (DKD), which major cause chronic leading to end-stage disease. Owing pleiotropic actions klotho, it shown beneficial effects DKD tackling complex pathophysiology reducing inflammation, oxidative stress, well fibrosis. Moreover, protective effect klotho extends beyond other conditions, cardiovascular diseases, alzheimer's disease, cancer, inflammatory bowel liver Therefore, this review summarizes relationship between expression diseases special emphasis on DKD, distinct mechanisms potential exogenous supplementation therapeutic strategy. Future research into could unravel novel treatment avenues for diseases.

The global derangement of mineral metabolism that accompanies chronic kidney disease (CKD-MBD) is a major driver the accelerated mortality for individuals with disease. Advances in delivery dialysis, composition phosphate binders, and therapies directed towards secondary hyperparathyroidism have failed to improve cardiovascular event profile this population. Many obstacles prevented progress field including incomplete understanding pathophysiology, lack clinical targets early stages disease, remarkably wide diversity manifestations. We describe review novel approach CKD-MBD combining mathematical modelling biologic processes machine learning artificial intelligence techniques as tool generation new hypotheses development innovative therapeutic approaches syndrome. Clinicians need alternative therapy, tools risk assessment, address complications course personalize therapy each individual. complexity suggests incorporating into diagnostic, therapeutic, research armamentarium could accelerate achievement these goals.
